'Landmark' in the Bible

Your neighbour's landmark, which was put in its place by the men of old times, is not to be moved or taken away in the land of your heritage which the Lord your God is giving you.

Cursed is he who takes his neighbour's landmark from its place. And let all the people say, So be it.

Let not the old landmark be moved which your fathers have put in place.

Do not let the landmark of the widow be moved, and do not go into the fields of those who have no father;

The rulers of Judah are like those who take away a landmark; I will let loose my wrath on them like flowing water.
